13 C im This invention relates to improved devices for securing calks or. cleatsto the soles of shoes,

particularly shoes used in various sports such for example as football andsoccer.

It is of the utmost impgrtance that the calks or cleats be so mounted that theywill not inad vertently become-loose and will be maintained in place even when subjected to the most severe usage.

It is, therefore, an object of the invention to provide a. calk device whichznay be most effectively held in place on a shoe sole. t

It is another object of the invention to provide a calk device which may be most easily applied to the sole.

One of the common expedients heretofore utilized in securing. calks or cleats to a shoe sole involves the provision of a threaded stud. e mes th hat s init lly fixe t9 the. stud, and the latter screwed intothe sole, and sometimes the stud is initially fixed to the sole and he chat th n sersw d. 9n the. studla ash o these variations of this expedient there is a problem of holding the calk and the threaded stud against turning and thereby becoming loose relative to the sole.

n t tan Ob o h e n t vention, therefore, is to providea calls device involving the use oi a threaded stud, in whieh the call: or cleat and the threaded stud are elffectively held against turning and unscrewing l fiY 9 h .5 i c I In the attainment of the above and other objects which will hereinaiter appear there is provided as a feature pf the invention a washer which may be ef feetively secured to the calk holding stud and which is provided not only with means for gripping the sole but also with pros iecting a er ldin h ta a a ns i advertent rotation.

which is inserted on the calk holding stud intermediate the base of the calkand the sole and is,

adapted to grip the base and hold the calk against. inadvertent rotation.

Fieg ew s mi r WFi but ho n anp be was e i t in t nother feature of "the invention resides in section, similar to Fig. 1, but showing the insert member in and the stemmed washer associated withthe is a detail. view looking downwardly he elk h ld ng Stadj 3 is aview partially in sectionv showing and first to Figs. 1 through 5, there is shown a 5 section of a shoe sole III which may be of conventional construction, including an inner or upper layer H and an outer or lower layer l2.

The calk device 13 provided by the present invention includes, as is conventional, a calk or cleat 14 of rubber or other suitable material, which as shown may be frusto-conical in shape and formed with a base I5 from which extends a threaded stem or stud 16. Preferably, webs l1 and I8 extending respectively longitudinally and transversely of the stud are provided to form a head [9 for locking the stud against movement relative to the calk I4.

As shown most clearly in Fig. 2A, the transverse web I8 is preferably of multisided form. Of importance it is to be noted that a plurality of recesses l8aare provided inthe edges of the transverse web to receive the body material of the calk l4 and thus serveto hold the stud against adverse rotation relative to the calk. Also of importance attention is directed to the fact that the longitudinally extending web I! is so formed and positioned that the side edges Ila and I'll) thereof extended outwardly to be in substantial alignment with two of the recesses l8a in the transverseweb l8.

With this construction the longitudinally exmovement in the calk body. And, of particular importance, the side edges |"la and ill) of the web I! by overlying the transverse web [8 define in effect notches into which the body material of the calk extends to further secure the stud against movement relative to the calk. Also, because the side edges I la. and [lb of the web I! extend beyond the edges of the transverse web I8 defined by the recesses l8a', a substantial thickness of supporting body material is interposed between the side edges Ila. and Ill) and the calk base. A very strong and efiective securement of the stud [6 in the calk is thus achieved.

For securing the calk to the sole l0 there is provided an interiorly threaded tubular insert member adapted to be inserted in a suitable aperture 2| in the shoe sole. A laterally extending flange 22 formed at one end of the insert member is adapted to overlie the upper side 23 of the sole and is provided with a plurality of circumferential disposed prongs 24 for engaging the sole and holding the insert against rotation relative thereto.

Of importance, there is associated with the insert member 20 a novel stemmed washer 25 having a deformable flange section 26 bent into substantially U-shape to provide portions 2! which extend away from the sole, and having an interiorly and exteriorly threaded tubular stem 28 adapted to be screwed into the insert memwhen the washer 25 is initially screwed in place but which, as shown in Fig. 3, are adapted to bite into and securely grip the sole when the washer is flattened. This feature is most advantageous in theassembly of the device as it is thereby possible to screw the washer tightly against the sole without interference with the prongs 33 and then subsequently to flatten the bent portions 21 to cause the prongs to grip and bite into the underside 34 of the sole. Moreover, because the prongs 33 are clear of the sole during the screwing up of the washer, they do not cut into the sole to form adverse grooves which would prevent the secure holding action achieved by forcing the prongs cleanly into an uncut sole. Also, the bent portions 21 offer a convenient means-for gripping the washer during the screwing or tightening operation. Thus, a worker may merely grasp the bent portions in his fingers and spin the washer into position, and if a pair of pliers or the like is used the bent portions may be easily gripped thereby.

Also of importance it is to be noted that pro- ..J'ections 35 are formed on the washer to extend toward the base l5 of the calk. As shown, the

projections 35 and the prongs 33 may be conveniently formed by lancing or by bulging out integral parts of the washer. However, they may be formed in any other suitable manner.

With this construction, when the threaded calk stud I6 is screwed tightly into the tubular stem 28 of the washer 25, the base I5 of the calk I 4 is drawn firmly against the gripping projections 35 and the calk is securely held thereby against inadvertent rotation relative to the washer 25 which in turn is held against rotation relative to the sole E2 and the insert member 20 by the prongs 33.

As shown a central recess 36 is formed in the base l5 of the calk for receiving the projections 35, and preferably a plurality of radially extending ribs 3! in the form of ratchet teeth are formed on the bottom 38 of the recess for cooperation with the projections 35 in holding the calk against unscrewing. The inherent resiliency of the projections 35 which are lanced out of the preferably metallic washer 25 causes the latter to act like spring pressed pawls. This action is accentuated when the calk and ribs 31 are formed of a compressible or resilient material such as rubber. Thus when the calk is rotated in one direction to be screwed toward the sole, the" inclined faces 39 of the ribs readily slide over the projections 35, butany tendency of the calk to rotate in the otherdirection is resisted by the projections engaging the substantially vertical sides 40 of the ribs. A very effective ratchet or locking means is thereby provided for maintaining the calk securely in position.

While, as shown, the ribs 3'! are in the form of ratchet teeth it will be readily understood that the ribsmay be formed either with two inclined faces or with two vertical sides. Such constructions will likewise serve to cooperate with the projections 35. in holding" the calk against inadvertent rotation, although not ,as satisfactorily as when ribs are formed 'to'simulatetrue ratchet teeth. 1

In the association of the calk device I3 with a shoe sole it is merely necessary to push the insert member .20 into a preformed aperture in the shoesole and embed the prongs 24 in the upper side :of the sole. The stemmed washer 25 is then screwed in place and'the bent; up portions 21 flattened by any suitable tool to force theprongs 33 into the underside of the sole. Then the threaded stud I6 is screwed e into the threaded be readily appreciated that thebottom-38amay be formed with gripping ribs as embodied in-the calk |4 shown in Fig.- 5. Likewise it will .be apstem of the (Washer to d-rawythe ribbed base of thecalk securely, against-the washer and into interengagement with theprojections 35.

,InFigs. 6 and 7 a modified form of calk device |3a is shown. In this form a calk Ma is provided which does nothave a stud initially fired thereto as in the form shown in Figs. 1 through 5, but whichincludes a calk holding screw meme ber 4| with a threaded shank 42 and a head 43, insertable in a preformed aperture 44 in the sole ll]. Whenthe screw member 4| is inserted in the aperture the threaded shank 42 projects downwardly through theaperture 44 to receive the modified .calk Ma and the head 43 overlies and is embedded in the upper side 23 of the sole. Preferably, andasshown, radially extending webs or fins 45 are formedon the head to bite into the sole and hold the screw member against adverse rotation. i

Of importance, there is provided with this modified calk device |3a a modified stemmed washer 25a which like the stemmed washer 25 first described has a deformable flange section 26 initially bent, as shown in dotted lines in Fig. '7, into substantially a U-shape to provide portions 21 whichinitially extend away from the sole but which are adapted, as shown in full lines, to be flattened on the sole and thereby force the prongs 33 into the underside of the sole. Also, like the washer 25, the modified washer 25a is formed with an interiorly threaded tubular stem 28a. which as shown, however, may be shorter than the stem 23 and provided with an unthreaded or smooth outer surface.

In associating the modified calk device with a sole, the screw member 6| may be first inserted in the aperture and the stemmed washer 25a then screwed thereon tov draw the tubular stem into the aperture 44 to thereby support the threaded shank in the sole.

. the sole.

The modified calk 14a, which preferably is provided with an internally threaded insert 46 embedded therein, may then be screwed on the threaded shank 42 and thus be drawn firmly against the washer 25 on the sole. As shown, the base |5 of the niodified calk is formed with a recess 36a having a plain bottom 3311 which is gripped by projections formed on the washer 25a exactly the same as the projections formed on the stemmed washer 25 first described. However, while the bottom of the recess 35a in the base of the. calk la is illustrated as plain it will The washer, therefore, is effecing the calk against adverse rotation, and which are initially formed with portions extending away 1 grips the main washer- 15b and the calk and preciated that if'desiredthe calk z|4 shown in Fig. 5, like the calk shown in Fig. 6, may be' Fig. '7, involves a calk |4b preferably provided with a threaded insert 46 and adapted to be screwed on the threaded shank 42 of a screw member 4| inserted in an aperture 44b formed in the shoe sole Hi. The screw member 4|, as shown, is exactly the same as the one illustrated in Fig. 7, with a head 43 provided with holding webs 45 and embedded in the sole.

In-the modified calk device |3,b-, a slightly modified washery25b is utilized which like the stemmed washer 25w shown in Fig. '7, has a threaded connection with the shank 42 of the screwmember. It maybe flatgorinitially bent into .a substantially .U-shape, as shown indotted lines, to ,provide portions initially extending away from the sole andformed with prongs 5| which advantageously may be lancedout of the j washer and are adapted to bite into the sole when the washer is flattened. However, as shown, no tubular threaded stem is formed on the washer, the threaded connection betweenthe washer 25b and the shank 42 being provided by asingle thread 58 defining theshank receiving, aperture in the washer. Such atubular stem may be provided, however, if desired. a Of particular importance there is inserted o the threaded shank 42 intermediate the main and preferably metallic washer 52 andthebase l5 'of the calk Mb a washer 53 of compressible material such as rubber or leather, which when the calkgis screwed tightly in place effectively holds the latter against inadvertent rotation.

Preferably, and as shown, projecting ribs 54 are pushed out of the main washer 25b to extend towardthe base of the calk. While these ribs 54 are shown as extending radially for'an appreciable extent they may, if desired be formed, like the simple projections 35 on the stemmed. washers 25 and 25a. Also, preferably ribs 31 are,-

formed in the recess 35 in the base ofv the calk Mb exactly the same as the rib-son the calk shown in Fig.5. With thisconstruction the ribs 54 on the main washer25b and the ribs 3! on the calk |4b bofth grip the compressiblewasher 53 and. the call; is thus most eifectively held 1 against adverse rotation.

This same compressible washer 53 may, if de sired-and;wi;th good effect, be utilized with each of the othencalk devices |3 and |3a shown in: Figsrl ,throughfl. When so'utilized the washer supplements the action of the projections 35 and ribs31 in firmly holding the calk and maintaining theisame in tightened position on the sole.

With each of the forms of the invention, washers are provided which have a threaded connection :with a member firmly embedded in the sole, which have projecting means for not o'nly gripping the sole but also for cooperating inholdircm the sole but adapted to be flattened and to push gripping prongs into the sole after the washer has been tightly screwed in place.
